Kalshi CEO Tarek Mansour endorses Rep. Ritchie Torres' push for a 2026 law banning insider trading by US officials in prediction markets, following high-profile Polymarket profits and record trading volumes.
Kalshi CEO Tarek Mansour has voiced support for Rep. Ritchie Torres' 2026 Public Integrity Financial Prediction Market Act, designed to ban insider trading by federal officials in prediction markets. The bill follows controversy over a Polymarket wager netting $400,000 from non-public information, raising concerns about misuse of privileged data. December 2025 trading volumes reached $6.26 billion for Kalshi and $2.28 billion for Polymarket, underscoring the scale of these markets. The legislation targets enforcement in regulated platforms like Kalshi and aims to enhance market integrity.
